To aZZw/w/"Lz' may-concern.' Y p .Be it known that I, AMos CALLEsoN, a

Brooklyn, in the county of Kings and State of New Yorlnvhave'invented certa-in new and useful Improvements in Sealing Appliances, of which the following. is a specification.

This invention relates to devices for attaching closures to vbottles of the class in which an annular expansible throat-forming series of closure attaching segments, into which the bottle head with the superimposed closure is forced, is embraced by a'yielding resistance means-such as vention contemplates va novel device of this class in which all parts of the resistance means yield together or as one when the bots tle head is forced into the'throat inthe act of afxinga closure, instead of successively,v

as where the resistance means is a series of parallel spring rings or a helical spring whose coils are woundprogressively along and around the axis of the throat, certain disadvantages of whichl are avoided by my construction, for instance, the rocking'of the segments so that they do not remain parallel with the throat axis during the entering and withdrawing movements of the bottle head, and excessive friction, which sooner or later coact to produce wear of the parts and cause breakage of bottles.

My invention distinguishes from prior art devices in its class in that it comprehends means to apply, to portions of the series of segments in planes remote from each other and transverse of the axis of the series, yielding resistance to the expansion of the series including a spring ring embracing said series and cut by both said planes and being rigid from one such plane to the other. V I prefer to employ a plurality of these rings, concentric and laminated, and to treat the ring or rings in certain novel respects with a view to producing additional advantageous results, all as will hereinafter appear.

In the drawing, i Y Figure l' shows in section a sealing head of a bottle sealing machine and my improved a closure aflixing device therein;

Fig. 2 is a plan of the device;

Fig. 3 is a side elevation of the device as shown in Fig. l;

Fig. 4 is a vertical sectional view of the device, showing a modification; and

Fig. 5 1s a perspective view of one of the spring rings.

isv formed between the end ofthestem b and a cupsshaped holder c secured onI the stem:

by the screw d, e `being the mouth of the orrica.

holder through which the, bottle head andsuperimposed closure arev admitted f. is'Y a.

plungerl which as the bottle and superimf` posed closure (which is assumed in thepresent instance to-be a crown of the well known type shown in. broken lines-at A) enter the'.

holder c opposes yielding resistance thereto. The bottom of the housing@ is formed by an apertured liner disk g; at the top of the housing is a hardened apertured dish Inherein shown inlaid inv the lower end of the stem 4 Y z' is an annular expansible throat-forming series of segments, preferably made of hardened metal and :formed'substantially the same Vasin my Patent ample; whenv this series. of segments expands or contracts as the bottle head and superimposed closure enter or leave Vthe throat' y' thereof, the wear incident to their movement is assumed by the disk 7a.

The means for opposing yielding resistance to the expansion of the series of segments is in the illustrated embodiment three concentric laminated spring `rings 73,' they are preferably, as shown, split rings, arranged so as to break joints, and to keep them in a definite relation may provide a (as by driving the metal by a sharp instrument from one side so as to producea proktuberance at the other) to engage in the split m, or an enlargement n thereof, in the neighboring ring. section and so presenting straight surfaces to the corresponding straight-incrosssec tion radially outer surfaces of the segments, or in any other way so that the means aforesaid applies yielding resistance tothe expansion of the series to portions thereof in planes remote from each other and transverse of the axis of the series, this annular medium embracing the segments and here shown for example as three rings allowsthe segments to move radially inward or outward substantially without tilting or rock-V ing out of parallelism with the axis. of the throat, de., out of parallelism with their rest positions, for each spring is rigid from one of said planes to theother.

To stiffen the rings, I may bend each of them continuously to form a channelA or No; 1,299,551, forex;

As by being straight in 'cross-V to each other I projection Z on one ringV loo `tinuous groove p crimp, as shown at 0 in Fig. 4, the channels coinciding with each other and with a conformed eXteriorly of and in the series of segments. By this means the parts comprising the device, to wit, the segments and rings, will be interlocked with each other. The rings, as shown, pret erably each have greater width than thickness.

So far as l am aware it is new in this art to utilize substantially concentric spring rings as the resistance means and this has the advantage over a single ring ot the same thickness of greater susceptibility to yield. therefore claim such substantially concentric spring rings broadly, .e., without reference to whether or not the form of said means and its relation to the segments is such as to prevent or substantially prevent their tilting. y

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is l. The combination of an annular expansible throatforming series of segments and means to apply, to portions of said series in planes remote from each other and transverse of the axis of the series, yielding resistance to the expansion of such series including a spring ring embracing said series andcut by both said planes and being rigid from one such plane to the other.

2. The combination of an annular eXpan sible throat-forming series of segments and means to oppose yielding resistance to the expansion of said series including substantially concentric. spring rings.

3. The combination of an annular expansible throat-forming series of segments and means to apply, to portions of said series in panes remote from each other and transverse of the axis of the series, yielding resistance to the expansion of such series including a spring ring embracing said series and cut by both said planes and being rigid from one such plane to the other, and another spring ring substantially concentric with and embracing the first ring.

4:. The combination of an annular eXpansible throat-forming series of segments and means to apply, to portions of said series in planes remote from each other and transverse or the axis of the series, yielding resistance to the expansion of such series including `a spring ring having greater width than thickness and embracing said series and cut by both said planes and being rigid from one such plane to the other, said ring having an annular crimp formed therein.

5. The combination or' an annular eXpansible throat-forming series of segments and means to oppose yielding resistance to the expansion of said series including laminated concentric spring rings interlocked with each other against slippage relatively to each other in one direction.
